RECWER FOR PRINTING-TELEGRAPHS.

SPECIFICATION formingpart of Letters Patent No. 663,859, dated December 18, 19=0.

` Application nea August 18,1896. serrano. 603,136. (Nomina.)

T0 1r/ZZ whom it may concern:

Be it known that I, JOHN BURRY, a citizen of the United States, and a resident of New York, (Astoria,) in the county of Queens and State of New York, have invented certain new and useful Improvements` in Receivers for Printing-Telegraphs, of which the following is a specification.

This invention relates to new and useful improvements in printing-telegraphs, and especially to a receiver for the same.

The object of my invention is to provide a new and improved printing-telegraph receiver i which is simple in construction, not apt to get out of order, can be operated at variable, high, or low speed, requires no skilled operators, and is especially adapted for use on private lines.

The invention consists in the combination, with a type-wheel having a series of circumferential rows of types and mounted to rotate in both directions and to be shifted in the direction of its length, front or back, of means for moving the same by an electric current and magnets.

The invention furtherconsists in the combination, with such type-wheel, of a magnet and coils on the same and an oscillating armature mounted tobe influenced and turned in either direction by the electric current passing through the coils, which rotary movements are resisted by a series of resistances, so as to permit of certain turning motion only for a given amount of current and a greater turning motion for a greater amount of current, which turning motions in one direction or the other `are transmitted to the type-wheel to turn the saine in either direction or to shift the same longitudinally in either direction.

The invention further consists in the combination, with the above elements, of an additional type-wheel and means for using either type-Wheel.

The invention also consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter and finally pointed out in the claims.

In the accompanying drawings, forming a part of this specification, and in which like letters of reference indicate like parts in all the views, Figure 1 is a perspective View of the motor mechanism of the receiver lof my 'use of synchronism or step-by-step or like movements, such as have been used in tickers or like printing-telegraphs heretofore; but I make use of two independent electric currents by varying the strength of the same and overcoming, by means of this current, resistances of different strengths, and thereby bringing the typewheel into different positions corresponding to the different strengths of currents and combinations.

The ends of the two shanks of the permanent magnet A are shaped to form acircular receptacle for a wire coil B, which is fixed in the same, the ends of the coil being connected with a line-wire and earth either in local battery or outside line. An iron armature-core C is mounted loosely in the center of the coil B and is .fixed on a shaft C', mounted in a frame U2 on the magnet A. O11 the opposite ends of said core C the two anchor-shaped arms or extensions D D', extending in opposite directions, are fixed. A check pin E, projecting from the upper edge of the armature D, can move between two stops E' E' for the purpose of limiting the turning motion of the armatures. A transverse arm Fis fixed on the shaft C' and is provided in'its upper edge,at each side of the shaft C',with one,two, or three or more notches F-in the case shown three on each sidewhich notches serve to receive the knife-edge pins G, projecting from slides G, suitably guided to move vertically and pulled'downward by helical springs G2 or analogous devices to rest normally on offsets H of various elevations above the plane of the shaft C. As shown, the `pins G' nearest the shaft C normally rest on an offset H and on the arm F, the next pins in the direction from the shaft' C' to either side on offsets H, higher than the shaft C, and the outermost pins G rest on still higher offsets H.

IOO

When current is passed through the coil B, the shaft C' is turned either to the right or left, according to the sign of the current, and one end of the arm F isv moved upward and the other downward. If the current has a certain predetermined strength, it can raise the arm F only sufficiently to overcomev the resistance of the corresponding spring G2 nearest the shaft to such an extent that the arm F comes in contact with the second pin G on the same side, but does not act on the pin or lift rit off the offset H; but if the `strength of the current is increased a predetermined amount the arm F is raised sufficiently to overcome the rst and second springs G2 on the same side and to come in contact with the outermost pin GQ without,

however, acting on the same. If the current is still further increased, the arm F is raised sufficiently to lift off all three pins G and stretch all three springs `G2 until the check.- pin E strikes against the corresponding stop E. In a like manner the other sidev of the arm F can be raised. The springs at any one side of the shaft C only begin to oder resistance as soon as the current turns the shaft C/ in such a manner as to lift the corresponding end of the arm F. When the said end of the arm descends to or below the horizontal, the correspondingv springs G2 cannot act, as their tension is taken up by the offsets H.

The movements of the arm F are not necessarily successive, as described, as sufficient current can be admitted at once to lift either end of the arm F to the eXtreme position, and the successive movement was only described to explain the operation.

The shaft C has an arm J, provided on its free end with a segment-rack J', engaging a pinion I on the shaft I, mounted in a frame l2, and on said shaft a type-wheel K is mounted in such a manner that it can slide on the shaft, but is compelled to turn with the same. The type-wheel has a series of annnlar rows of type characters, there being a like number of type characters in each row, and each circumferential row has twice as many type characters plus one as there are different positions or resistances on each side ofthe shaft C'. For example, six springs G2 are shown in the drawingsthat is, three on each side-and consequently there must be seven type characters in each circumferential row.' Three different strengths of current are required both for negative and positive, giving six positions, to which must be added the position of rest,which gives seven, as above. Y

When only two springs or other resistance's are provided for each end of the arm F, we have five positions, including the position of rest, and therefore there must be five type y characters on each circumferential row on the typewheel,and when only one spring or other resistance is provided for each end of the arm F we have three positions, and therefore therel must be three characters on each circumferacter.

eeaste ential row of the type-wheel. The type-wheel can thus be turned to present as many longitudinal rows of characters as there are resistances for the arm F plus one, and it now remains to shift the type-wheel longitudinally to bring the circumferential row bearing the desired type character into proper position, the type-wheel being turned circumferentially at the same time for this required character. To produce this longitudinal movement,an additional magnet-coil and armature, dac., are provided, like the one described, at substantially right angles to'those described. The arm L of the armature-shaft of this additional magnet A terminates in a hook or bend L2, which passes into the centralgroove between two circumferential rows of type characters, so that when said shaft is turned in one direction or the other it shifts the typewheel longitudinally a greater or less distance, according to the strength of the current used, and in one direction or the other, accordingly as a positive or negative current is used. With seven circumferential rows of seven type characters each forty-eight positions can be obtained, as there must be a position of rest which corresponds to one char- With five circumferential rows of five characters each twenty-four positions can be obtained, and with three circumferential rows y of three characters each eight positions can be obtained.

In addition to above combinations the apparatus can be so arranged as to have a different number of positions by rotation from those obtained by shifting. For example, there may be seven characters in each circumferential row and only five or only three of such rows-that is, the type-wheel would be shifted longitudinally into only five or three positions, respectively.

It is evident that the type-wheel may have more than seven characters in each circumferential rowrbut this number should preferably be equal to twice the number of strengths of current plus one used for turning, and the number of changes by shifting should be equal to twice the number of strengths of current plus one used for shifting longitudinally.

The receiver must be provided with means for feeding a paper strip, an inking device, and means for pressing the strip of paper against the type-wheel. This may be accomplished in various ways, and many of the old and Well-known devices may be used for this purpose; but I prefer to use the mechanism now to be described.

The lever M, pivoted at M', carries at one end the armature M2 of the press-magnet M3 and at the other end the block M4 for pressing the paper strip N against the type-wheel andinking-ribbon P. The paper band or tape N is wound on a reel N and passes over the guides N2 N2 and over the feed-wheel N3 on the end of the shaft O on which the ratchet-wheel N4 is fixed, that is engaged by the hook-pawl N5,

IIO

operated by the lever M and the check-pawl N6. The spring-pressed roller N7 presses the paper strip or tape upon the feed-roller N3. A Worm O is formed on one end of the shaft O' of the paper-feed wheel N3 and engages a worm-wheel formed on one of the two spools O2, over which the endless hiking-ribbon P passes. Each shaft C carries a disk Q, in the rim of which a piece Q of insulating material is countersunk in such a manner that said piece is at the top when, no current is passing, and on said disk Q a brush R rests, which is non-conductively attached to the frame of the machine. As shown in diagram Fig. 5, the brushes R of both magnets are connected with a local battery T, which in turn is connected with the press-magnet M3, and the latter is connected with the frame.

I/Vhen both brushes R rest on the insulating-pieces Q', the entire local-battery circuit is broken; but as soon as current is admitted into either coil B and the corresponding shaft C' is turned the corresponding brushes slide off the piece Q and the local circuit is closed as follows: from the local battery T to the press-magnet M3, the frame of the machine, the shaft C, the disk Q, brush R, back to the local battery. Thus the press-lever is operated by its magnet M3 every time current is admitted into the coil of either magnet A.

As shown in diagram Fig. 7, relays may be used for the local battery. Each coil B, instead of having its second terminal connected With the earth, as shown in Fig. 5, is connected by a wire e with a relay-magnet f, which in turn is connected with the earth. The armatures g of the relays close the circuit of the local battery T, in which the pressmagnet M3 is arranged. Whenever current passes through either line L or L2 to either coil B, the corresponding relay closes the local circuit and the press-magnet operates the printing or pressing lever M,

In place of using but one type-wheel two type-wheels c 7c', parallel to each other, may be used, which turn and slide longitudinally together, but bear dierent type characters. Below each type-wheel a press-plate Z Z is located and below them the shiftable presserhead m on one end of a sleeve n, mounted to slide on a rod o. A pivoted lever 1J engages said sleeve u, so that when said lever is swung to one side or the other the sleeve is shifted and the presser-head m brought under the plate Z or Z. At each side of the lever p a permanent bar-magnet q q is located in such amanner that the north poles face eachother, andon the north end of each magnet two coils r r s s are secured. The coils r and s and r and s are wound and connected so that if a strong positive current passes through the lines Il L2 the strength of the magnetism is increased in the end X and decreased in the end Z, and if a strong negative current passes through the lines L L2 the strength of the magnetism is increased in the end Z and decreased in the end X, and thus Vthe leverp is shifted to the left or right and net lever can pass for the purpose of correct-v ing any slight inaccuracies in the positions of the type-wheel.

Having thus described my invention, what I claim as new, and desire to secu re by Letters Patent, is-
